4 MPC837xE-RDS Software
The MPC837xE-RDS comes with a pre-installed reference design software package. This package
consists of a bootloader (u-boot), a generic PPC Linux-based system, and a suite of Wi-Fi router
applications. The software all resides in the on-board Flash memory. Upon powerup, the Linux system and
the applications run on the MPC837xE-RDS.
The MPC837xE-RDS reference software takes advantage of a tool called OpenWRT, a Linux platform for
embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable
file system with package management. This frees you from the application selection and configuration,
allowing you to customize the device through the use of packages to suit any application.
